Well I did it on my t440p and I didn't find it entirely trivial including the risk that you may brick the motherboard and that the Laptops sold over their are additionally refurbished if I understood correctly … So £130 is not too much in my opinion. Obviously it is on the high side because low volume and support for free software ·

I can't give a specific example sadly. In my opinion it is not the best bang-for-buck because you need to luck for that specific model and the needed parts. I think you can find better deals if you are open e.g. for other Thinkpad models that are currently sold at a better price in your country but can't run Libre/Coreboot. I think T440ps are already out of the "companies are dumping them on the used market"-window so their are probably better deals with a bit younger models …

Would agree with that. Great Linux machine with that extra kilometer of freedom. With an upgraded CPU still powerful enough for 2023 and probably a few years to come. Probably one of the most powerful systems you can get with (nearly) free firmware and while not the best bang for the buck, probably the best bang for the buck for freedom that's available. I think all other systems with libre firmware are either way more expensive or less powerful …

Would add to your points:

* Rather heavy for a laptop (at least for my taste).

* Very upgradeable, much cool!

* You probably want to upgrade the touchpad to get separate trackpoint buttons.

* To flash the firmware yourself you need to get access to both BIOS chips. To get to the second BIOS chip you need to nearly completely disassemble the machine. While not necessarily difficult to do, their is a good chance you have PTSD from breaking plastic clips afterwards …
